That resembles a bug!  I would expect
\alternative { { a1 } { a1 a1 a1 a1 } }
to give a 4 bar 2nd ending (draw the horizontal line for 4 bars).

I hope a developer will check in here.

I just found an example where Lily gives me a right vertical bar.  (The 
score I copied the part from does not have the right vertical bar).  In 
this case the  measure has less beats than a full bar and is followed by 
a double bar.  From  this and your example I might guess that it is the 
presence of a double bar or other special bar that causes the right 
vertical bar.

Would it take care of your needs if I'm right about the double, etc. bar 
causing the closing vertical bar?

Looking a little more I find some examples of each style in my published 
music.

Let's see if we get developer input here.
